SmoothSteve3 Posted November 4, 2003 Report Share Posted November 4, 2003 Hey everyone- I'm thinking about doing an upper engine rebuild this summer.....like porting the upper and lower intakes, and porting the heads with a 5 angle valve job too. You guys think its worth it? I'm gonna replace my valveterrain while i'm in there too.....just give me your thoughts. SmoothSteve Quote Link to comment Share on other sites More sharing options...
slick Posted November 4, 2003 Report Share Posted November 4, 2003 Yeah, i'd do. Should feel some gains. Might help if you get a larger bore throttle body, and some sort of free-er flowing air intake. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted November 4, 2003 Report Share Posted November 4, 2003 The 5 angle valve job isnt worth it, replacing the springs isnt really worth it, basically replacing stuff isnt worth it. Only if you port the heads properly and match them to the lower and upper intake will you see gains. Quote Link to comment Share on other sites More sharing options...

The money he will pay for the 5 angle job is not worth the maybe 1HP he will see from it. If he was forced induction, then maybe I could see it Quote Link to comment Share on other sites More sharing options...

SmoothSteve3 Posted November 5, 2003 Author Report Share Posted November 5, 2003 Yeah, I just figure that I might as well replace some of the valve terrain while I have it right in front of me. I'm getting ready to buy a pair of used heads for 50 bucks....so i figure i can port and refurbish them. But thanks a lot for the suggesstion about not doing a 5-angle valve job. Thats a lot of money saved right there. Hopefully, my upper and lower intakes will be in this week! SmoothSteve Quote Link to comment Share on other sites More sharing options...
